CHAIR.

Specification of Letters Patent.

Patented June 4, 1907.

Application tiled February 16, 1906. Serial No. 301,379.

.To all wiz/0m, it may concern.-

Be it known that I, JAMES E. HANGER, a citizen of the United States,residing at Vashington, District of Columbia, have invented certain newand useful Improvements in Chairs, of which the. following is aspecification.

This invention relates to improvements in chairs, and more particularlyto the construction and arrangement of the back and seat portions.

The object of my invention is to provide a chair back constructed of aseries of slats curved'at or near their lower ends in such a manner asto forni a perfect support for the small of the back, and straight attheir tops so as to properly support the shoulders, the i said slatsbeing connected to each other and to the frame of the chair by atransverse spring or springs which allow the entire series as well asthe individual slat to accommodate or adapt itself or themselves to thecurvature or form of the back, and thus insure perfect ease and comfortto the occupant.

Another object of my invention is to pro vide a chair seat so mountedupon the frame as to have a rocking or oscillating` movement, which iscontrolled by a coiled spring so .arranged as to allow the seat to tiltbackward sufficiently to adapt itself to the form of the occup ant anddistributing the pressure evenly, thus affording great ease and comfort.

Iith these ends in view and such others as may hereinafter appear, myinvention consists in certain component and co-operative part-s, and inthe novel manner of combination and arrangement of said parts, all ofwhich will be more fully described and specifically pointed out in theappended claims.

In the drawings formingva part of this specificationz-Figure 1, is avertical sectional view of a chair illustrating my invention as applied5 Fig. 2, is a front view of a chair illustrating theback; Fig. 3, is aplan 'view illustrating the slats and transverse springs g Fig. 4, is asimilar view illust-rating a modification; Fig. 5, is a similar viewillustrating another modification, and Figs. 6 and 7 are perspectiveviews of the clamps for retaining the slats to the springs.

Referring by numerals to the drawings, 1 represents the legs of thechair which extend up sufliciently above the seat to form a support forthe arms 2. These legs are secured together by horizontal braces 3, andtransverse braces 4, and 5, the braces 8, support a transverse rod 6,which is a little front of the center of the chair and provides apivotal support for the seat 7, the forward end of which is normallyheld against the transverse brace 4, by coiled springs 8, wound upon therod 6, with one end extending forward and secured in the braces 3, whilethe other end extends in the opposite direction and engages the bottomof the seat which is limited in its movement by the transverse brace 5,however, a sufficient movement is provided to allow the seat to adaptitself to the'desired inclination to render ease and comfort to theoccupant.

The frame for the back of the chair consists of parallel side sections 9and transverse braces 10.- This frame may be stationary or pivoted, asdesired, and provided with a head-rest 1 1, or such head-rest may beeliminated. Mounted upon transverse springs 12, which are secured ateach end to the respective side sections 9, area series of slats 13,which are straight at their upper ends 14, and curved at or near thelower ends as shown at 15, to fit the small of the back. Thesetransverse springs which maybe one or more, as desired, consists of asteel spring wire bent at regular intervals to form a U- shaped loopslightly contracted at the neck, to which is secured the slat 13, bymeans of clamps 16, and 17, which are so constructed as to allow aslight movement of the spring portion held therein.

On Fig. 4, I have shown a modification of the transverse spring whereinthe spring consists of two steel wires 18 and 19, bent in a zig-zagmanner in reverse directions and secured to the slats by the clamps 16and 17, so that each wire will be permanently secured to every otherslat, and have a slight movement in the clamp securing it to theintermediate slat, the permanent and loose clamps alternatingthroughout.

In Fig. 5 I have shown another modification wherein the transverse wireis coiled as shown at 20, around a stud 21, upon the back ofthe slat.This form as in the case of the forms above described, may be usedseparately or in conjunction with others, however, I have found that twoof such springs give the best result-s.

Minor changes in the transverse spring, such as connecting the slats byintermediate spiral springs, and other details of construction, may beresorted to without sacrificing the advantages of my invention.

Having thus described the various features of my invention, what I claimas new and desire to secure by Letters Patent, is

1. In a chair back, the combination with the trame, a transverse spring,a plurality of independent slats secured to said spring, substantiallyas specified.

2. In a chair back, the combination with the frame, transverse springssecured upon theframe, a plurality of independent slats iecured to thesprings, substantially as speci- 3. In a chair back, the combinationwith the frame, a series of transverse s rings secured to the sides ofthe frame, a p urality of independent slats clamped to the springs,

substantially as speciiied.

4. In a chair back, the combination with the frame, a transverse springconnecting the sides of the frame, a plurality of independentV slatssecured upon the spring, the upper ends of the slats being straight andthe lower ends curved, substantially as specied.

5. In a chair back, the combination with the frame, a series oftransverse springs connecting the sides of the frame, a plurality ofindependent slats curved at their lower ends, ineans for securing theslats to the springs, substantially as specied.

6. In a chair back. the combination with the frame, two transversesprings composed of a series of loops connecting the sides ofthe frame,a plurality of independent slats curved at their lower ends, means forsecuring the slats to the loops, substantially as specified.

7. In a chair back, the combination with the frame, two transversesprings composed of a series of U-shaped loops the ends of which aresecured to the sides of the frame, a plurality of independent slatsbeing straight throughout a portion of their length and the otherportion curved, and means for securing the slats to the said loops,substantially as speciiied.

8. In a chair back, in combination with the frame, a plurality oftransverse springs, the respective ends of the springs being secured tothe sides of the frame, each spring being composed of a series of loops,aiplurality of slats, each slat being straight throughout a portion ofits length, and curved throughout the remaining portion, and means forsecuring the slats to the loops, substantially as specified.
